GENERAL SPECIFICATIONS

Connection

Internal bus: Via the Installation Base (model: R3-BSx)

Output: M3 screw terminals (torque 0.5 N·m)

Internal power supply: Via the Installation Base (model: R3-

BSx)

Screw terminal: Nickel-plated steel

Isolation: Output 1 to output 2 to output 3 to output 4 to

output 5 to output 6 to output 7 to output 8 to internal bus

or internal power

Output hold setting: Setting for communication error with

side DIP SW

RUN indicator: Bi-color (red/green) LED;

Red when the bus A operates normally;

Green when the bus B operates normally;
